[0026] S7: After completing wastewater treatment, shut down the equipment, remove the filter to clean the residual materials, and perform maintenance on the equipment.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, a treatment cylinder, a cylinder cover, a first slide groove, a water reservoir, a connecting pipe, a stirring rod, a blocking strip, a spring, a second driving motor, a first gear, a second gear and a wedge strip are provided. Under the action of the second driving motor, the first gear will be driven to rotate accordingly. At this time, the first gear will drive the second gear to rotate on the stirring rod, and the second gear will drive the wedge strip to rotate with its midpoint as the central axis. When the wedge strip contacts the blocking strip, the blocking strip will be squeezed and move downward inside the first slide groove. At this time, the blocking strip will be separated from the cylinder cover. At this time, the chemical reagent inside the water reservoir will flow into the treatment cylinder through the connecting pipe. At this time, the blocking strip will drive the spring to stretch accordingly. When the wedge strip and the blocking strip are misaligned, the spring will drive the blocking strip to reset and block the two connecting pipes, so that the device can intermittently add chemical reagents. Adding reagents in stages can fully promote the reaction at different stages, avoiding excessive or low local concentration caused by one-time addition, thereby improving the overall reaction efficiency.

[0029] In the present invention, when the chemical reagents and certain ions in the wastewater (for example, heavy metal ions, alkaline earth metal ions, phosphate ions, fluoride ions and arsenic ions, etc.) form precipitation and are removed, stirring can accelerate the fusion speed of the wastewater and the chemical reagents, promote the precipitation reaction to proceed fully, improve the utilization rate of the chemical reagents, and reduce the cost of wastewater treatment;

[0030] In the present invention, a treatment barrel, a first stirring blade, a second stirring blade and a floating plate are provided. When waste liquid is injected into the treatment barrel, the three floating plates are affected by the buoyancy of the waste liquid and drive the three second stirring blades to slide inside the three first stirring blades, so that the three floating plates can always float on the water surface, so that the stirring blades of the device can be adaptively adjusted according to the capacity of the waste water, and at least three second stirring blades can always be combined with the three first stirring blades to form a funnel shape, which helps to guide the material to flow along a specific path and avoid dead corners or accumulation of the material in the stirring container. The funnel shape will produce different fluid flow patterns during rotation, promote the mixing and circulation of waste water and chemical reagents, make the stirring more sufficient and uniform, and improve the reaction efficiency and treatment quality.

[0031] In the present invention, by providing a water outlet, a rubber plug, an inner rod, an impact head, a limit strip, a second driving motor, a second gear, a screw and a wedge strip, the wedge strip can be adjusted upward by rotating a threaded ring on the screw during unloading. When the wedge strip and the limit strip are located on the same horizontal line, the rubber plug can be pulled out of the water outlet. At this time, when the second driving motor drives the second gear and the wedge strip to rotate, the wedge strip will contact the limit strip, and the limit strip will be forced to drive the inner rod and the impact head to move upward. When the wedge strip and the limit strip are misaligned and separated, the impact head will impact in the water outlet under the action of gravity, thereby clearing the water outlet, reducing production interruptions and equipment failures caused by blockage, and improving the continuity and reliability of the entire production process.

[0032] In the present invention, a filter screen, a stirring rod, a rotating rod and a spring are provided. When the stirring rod rotates, the rotating rod limited by it will be driven to rotate accordingly, and the rotating rod is in a state of being in contact with the filter screen. Therefore, the impurities trapped on the filter screen will be scraped under the rotation of the spring, which can effectively prevent the filtered impurities from clogging the filter screen. The device can keep the filter channel unobstructed and improve the filtering efficiency and sustainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] A process for using a chemically purified wastewater treatment device comprises the following steps:

[0049] S1: Check whether all parts of the equipment are normal and ensure that the chemical reagents are adequately prepared and placed inside the water storage tank 24;

[0050] S2: Pour the chemically purified wastewater into the treatment barrel 11 through the water inlet on the barrel cover 21. The wastewater first falls to the filter screen 17 for filtration and then flows into the interior of the treatment barrel 11.

[0051] S3: injecting waste liquid into the treatment tube 11, the three floating plates 53 are driven by buoyancy to slide the three second stirring blades 52 inside the three first stirring blades 51, so that the stirring blades always float on the liquid surface and are in a funnel shape;

[0052] S4: Rotate the threaded ring 47 on the screw rod 46 to adjust the height of the side block 49 and the wedge bar 48 downward until the wedge bar 48 and the blocking bar 36 are on the same horizontal line;

[0053] S5: Start the first drive motor 26 and the second drive motor 41. The first drive motor 26 drives the stirring rod 27 to rotate. When the stirring rod 27 rotates, it drives the rotating rod 34 to rotate to scrape the impurities trapped on the filter screen 17. At the same time, the first stirring blade 51 and the second stirring blade 52 stir the wastewater. At the same time, the second drive motor 41 drives the first gear 42, the second gear 43 and the wedge bar 48 to rotate. When the wedge bar 48 contacts the blocking bar 36, the chemical reagent flows from the water storage tank 24 through the connecting pipe 25 into the treatment cylinder 11 to react with the wastewater.

[0054] S6: When unloading, the threaded ring 47 is rotated on the screw rod 46 to adjust the wedge strip 48 upwards so that the wedge strip 48 and the limit strip 33 are at the same level, and then the rubber plug 14 is pulled out, and the wedge strip 48 rotates to contact the limit strip 33 to drive the inner rod 31 and the impact head 32 to move upwards. When the wedge strip 48 and the limit strip 33 are misaligned, the impact head 32 impacts the water outlet 13 under the action of gravity to dredge it;

[0055] S7: After the wastewater treatment is completed, the equipment is turned off, the filter 17 is removed to clean the residual substances, and the equipment is maintained.

[0056] Working principle:

[0057] In the first step, when in use, the chemically purified wastewater can be poured into the treatment barrel 11 from the water inlet on the barrel cover 21. At this time, the wastewater will first fall into the filter screen 17 to be filtered, and then flow into the treatment barrel 11. Then the threaded ring 47 can be rotated on the screw 46 to adjust the height of the side block 49 and the wedge bar 48 downward. When the wedge bar 48 is adjusted to be on the same horizontal line as the blocking bar 36, the first drive motor 26 can be started at this time. Under the action of the first drive motor 26, the stirring rod 27 will be driven to rotate accordingly. At this time, the stirring rod 27 will drive the first stirring blade 51 to rotate accordingly, and the first stirring blade 51 will drive the second stirring blade 52 to rotate accordingly. Under the joint action of the first stirring blade 51 and the second stirring blade 52, the wastewater inside the treatment barrel 11 will be stirred. At the same time, the second drive motor 41 can be started. Under the action of the second drive motor 41, the first gear 42 will be driven to rotate accordingly. At this time, the first gear 42 will drive the second gear 43 to rotate on the stirring rod 27, and the second gear 43 will drive the wedge bar 48 to rotate. The blocking bar 36 rotates with the center axis at point 22. When the wedge-shaped bar 48 contacts the blocking bar 36, the blocking bar 36 will be squeezed and move downward inside the first slide groove 22. At this time, the blocking bar 36 will be separated from the cylinder cover 21. At this time, the chemical reagent inside the water storage tank 24 will flow into the treatment cylinder 11 through the connecting pipe 25. At this time, the blocking bar 36 will drive the spring 37 to stretch accordingly. When the wedge-shaped bar 48 and the blocking bar 36 are misaligned, the spring 37 will drive the blocking bar 36 to reset and block the two connecting pipes 25, so that the device can add chemical reagents intermittently. Adding reagents in stages can fully promote the reaction at different stages, avoiding excessive or low local concentration caused by one-time addition, thereby improving the overall reaction efficiency; forming precipitation with certain ions in the wastewater (for example: heavy metal ions, alkaline earth metal ions, phosphate ions, fluoride ions and arsenic ions, etc.) and removing them, and then stirring can accelerate the fusion speed of wastewater and chemical reagents, promote the full progress of precipitation reaction, improve the utilization rate of chemical reagents, and reduce the cost of wastewater treatment;

[0058] In the second step, when the waste liquid is injected into the treatment barrel 11, the three floating plates 53 are affected by the buoyancy of the waste liquid and drive the three second stirring blades 52 to slide in the three first stirring blades 51, so that the three floating plates 53 can always float on the water surface, so that the stirring blades of the equipment can be adaptively adjusted according to the capacity of the waste water, and at least three second stirring blades 52 can always be combined with the three first stirring blades 51 to form a funnel shape, which helps to guide the material to flow along a specific path and avoid dead corners or accumulation of materials in the stirring container. The funnel shape will produce different fluid flow patterns during rotation, promote the mixing and circulation of waste water and chemical reagents, make the stirring more sufficient and uniform, and improve the reaction efficiency and treatment quality;

[0059] The third step is to adjust the wedge strip 48 upward by rotating the threaded ring 47 on the screw rod 46 during unloading. When the wedge strip 48 and the limit strip 33 are on the same horizontal line, the rubber plug 14 can be pulled out of the water outlet 13. At this time, when the second drive motor 41 drives the second gear 43 and the wedge strip 48 to rotate, the wedge strip 48 will contact the limit strip 33. The limit strip 33 is subjected to force and will drive the inner rod 31 and the impact head 32 to move upward. When the wedge strip 48 and the limit strip 33 are misaligned and separated, the impact head 32 will impact in the water outlet 13 under the action of gravity, thereby clearing the water outlet 13, reducing production interruptions and equipment failures caused by blockage, and improving the continuity and reliability of the entire production process.

[0060] In the fourth step, when the stirring rod 27 rotates, the rotating rod 34 limited by it will be driven to rotate accordingly, and the rotating rod 34 is in a state of being in contact with the filter 17. Therefore, the impurities trapped on the filter 17 will be scraped under the rotation of the spring 37, which can effectively prevent the filtered impurities from clogging the filter 17. The device can keep the filter channel unobstructed and improve the filtration efficiency and sustainability.
